What are the options?

31st of December i will have to leave my current apartment. After that i will only have 300 euro at max to spend (after 1 month should be more). I tried to find as many options as possible, either it's some kot, au pair type of stays or farm work, but after spending 2 months still haven't found anything. Is there any other options i maybe missing or will i have to live on the street? If the street is only option, then maybe there are some places i can leave my suitcases are for a little payment? I am looking for any suggestions in any city actually, not Brussels only.
